摘要
含对硝基氯苯的工业废水中的含量测定,可在还原、重氮化、与二盐酸 N-(1-萘基)乙二胺偶合后在557±2nm 处进行比色测定。工业废水中存在的其它硝基物和氨基物在含量不高时对测定影响不大。该法回收率平均98.2%。
The content of p-nitrochlorobenzene in industrial waste water was colorime-trically determined at 557±2nm.The interferences due to small amounts p-ni-trophenol,p-nitrophenyl ethyl ether or p-aminophenyl ethyl ether are negligible.This methodts simple,rapid,and reproducible with average analytical recovery98.2%.
